how did you manage to downgrade without errors?
No matter what version i downgrade to i lose baseband and get FC's on com.xxxx.phone which results in a boot loop, i then have to use the Companion to repair back to 6.0.1
EDIT
Fixed It, had a sneaky ta file while flashing the .ftf

Now that the X1S is out officially, perhaps someone can export the apk from their phone to be flashed on international Z1 version? I wasn't able to use the wifi calling apk I exported from a Tmobo Z (deodex fail etc), maybe the Z1S is similar enough to allow it.
And if you could file that TPS report, that would be greaaat...
I was curious about just flashing the entire Z1S ftf for that same reason but decided against it

If you need your Z1 don't do that
To try flashing without kernel - wouldn't recommend even that, but whole ftf will most probably cause bricked device.

FTF files are official firmware packages from SONY for our Xperia Smartphones.
Flashing them, we get what SONY offers to our phones.
We differentiate them by the build number.
Look out for the FTF files in our forum to know more about them, Or you are free to ask more questions/PM me about it

You can flash stock FTF via flashtool...
If you want to use PCC or SEUS,you have to relock your bootloader...
After flash through flashtool.will bootloader get locked

No.
Your boot loader won't get locked if you flash your firmware. But you can lock your boot loader with your drm keys intact if you have taken a back up of the keys. It is said you can relock your bootloader even without the drm keys. But don't know how much that would help in pcc or sus.

Use doom lord's toolkit to root your phone.
Hello, I am new to Sony and Samsung come see that changing here is more complicated software, cell ny is a J-ST26A Xperia-rom and version is the 11.2.a.0.31 and I want to root the phone, tutorials I have seen that they are very long and complicated (change the kernel, use flashtool, remove the battery). I found a much easier method is to DooMLoRD easy root toolkit in which the last version added support for this phone. The forum said it was compatible with the ST26A st26i (I have the ST26A) and was consistent with the version 11.2.a.0.31 and 11.2.a.0.21 (mine is .31). What I wanted to ask is if someone rooted a mobile with the same characteristics as mine (ST26A-11.2.a.0.31), and let me know if it works and no signal loss problems as bricks or something, it would be helpful I answered that I really want to be root thanks. DEVICE: ST26A ROM: 11.2.A.0.31 (JELLY BEAN) BOOTLOADER: Locked
Sorry for my english but I using the google translate
I is fot International, A is for American. So I think that you can root your phone with out problem. I have st26i, roote with DooMLoRD.

You can repair with PC Companion of Flashtool. But it won't brick if you follow the steps.

Part of rooting is to install SuperSu so you'll only need to update it later.
